Biological Activity
Mefloquine HCl is an antimalarial drug and blood schizonticide that acts by inhibiting hemozoin formation in Plasmodium parasites. It targets the Plasmodium falciparum 80S ribosome to inhibit protein synthesis and selectively blocks Cx36 and Cx50 gap junction channels. Through the inhibition of ribosomal translation and disruption of intercellular connexin signaling pathways, Mefloquine HCl suppresses parasite survival and alters cellular communication. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).

Pre-aliquoted for Longevity: Solid-state aliquots offer longer shelf life compared to stock solutions.
